You might have trekked the mountain paths or the thick forests. You might have had to scramble up the rocky mountains. Or may be crossed a fast running stream. At the end of the day, you are dead tired. All you are thinking of now is the cozy warm comforts of your sleeping bag. And you know that you have to get up early the next day for yet another arduous trek ahead no less exciting. The sleeping bag simply becomes your heavenly bliss.
But does the sleeping bag that you have with you give you all that you desire? Of course, a synthetic fill bag is much cheaper than a down fill bag. It is easier to clean a synthetic bag. But it is the insulation that is critical where you are now. It is the ground on which you decide to lay down to sleep decides how much insulation you need. If it is a wooden floor, it is warmer than a cement floor which is cold. A hut or an open space brings in all the chill wind rather than a protected camping tent.
The down fill bag is warmer than the synthetic fill bag. But the insulation is better with the synthetic bag. The insulation lasts longer too. The down fill bag is better for the cold winter as it keeps you warmer. The down bags are lighter. They are ideal for taking along with you if you plan for a longer trip. But they need to be taken good care of so as to prevent damages. These last longer and are durable. The down bags are also costlier.
The rectangular sleeping bag is more spacious than the mummy shaped bag. But the insulation of the mummy bags is better than the rectangle bags. While the mummy shaped bags are rolled, tied and packed into a sack, the rectangular bags can be folded and secured using straps or chords. The helium marmot bag is ideal for long treks, particularly up into the mountains.
Choose your sleeping bag keeping the weather, the environment and the duration of your travel. Check whether it is dry or wet climate. You will not regret this.
